Abstract

This database gives hydrogen-deuterium exchange mass spectrometry (HDX-MS) data from measurements of three purified IgG1 glycoform samples, predominantly G0F, G2F, and SAF, in isolation and in complexation with the high-affinity receptor, FcγR1a (CD64). The IgG1 antibody used in this study, aIL8hFc, is a murine-human chimeric IgG1, which inhibits IL-8 binding to human neutrophils. The working datasets comprise 17,750 deuterium uptake measurements in peptides from the receptor and the light and heavy chains of aIL8hFc obtained during 7 experiments, each comprising three runs of six exchange times. The data illuminate on the hydrogen exchange dynamics in isolated receptor, isolated IgG1 glycoforms, and receptor-IgG1 complexes.
